But one woman, a mother of two young daughters, decided to take a summer vacation from at least one device -- her smart phone.

She said it wasn't easy. But the rewards are great, especially for her kids.

Jessica McDaniel has a thriving baby photography business. She depends on emails and Facebook to keep it that way.

But for the second summer, from June through August, she virtually shut down her iPhone, inspired by her 4 and 7-year-old daughters.

"It's like shaking an addiction. I used to pick it up and put it down. It was calling to me," said McDaniel.

But there was no going back, once she made the promise to her older daughter.

"To have her eyes light up when I suggested the idea of it, it made me kind of horrified to imagine what is she seeing of me with my face in my phone. I want them to remember snacks after school, talking about their day instead of mommy saying, 'I just have one more email to reply to,'" said McDaniel.

The mother of two is a realist. Her business keeps her at the computer for many hours a day, while the kids are at camp. She does use her phone to make calls and occasionally text. And come September, the phone goes back on full service. But for now, the summer rule sticks and the phone is no threat.

"In the summer it feels like a brick,"said McDaniel.

McDaniel hopes her time off will serve her children well, as they grow up and navigate their own digital world.

"They are 7 and 4, so I feel like this is my chance," McDaniel said. " I feel like I'm sort of trying to model the behavior."

McDaniel said she knows her smart phone vacation is not for everyone, or even possible. Having her own home business makes it easier to follow through. But her advice is to take even a day or two off from the all the buzzing and flashing. She said it can be very therapeutic for everyone.
